IMPROVEMENT IN LAMPS.

Specification forming part of Letters Patent No. 167,113, dated August24, 1875; application filed March 12, 1875. I

To all whom it may concern:

Be it known that I, STEPHEN S. NEWTON, of Binghamton, Broome county, NewYork, haveinvented certain Improvements in Lamps, of which the followingis a specification My invention consists in the combination of aremovable wire-gauze chamber, attached to a supplementary collar, and anon-conducting collar and burner; the object of the invention being toprevent the lamp from exploding, and to readily remove the wire-gauzechamber for cleaning; also, to obviate the heating of the partsconnected with the burner, and the smoking and blurring of the chimney.The invention comprises a new arrangement of parts, which will hereafterbe fully described.

Figure 1 in the accompanying drawing is a lamp embodying my invention,with a section of the shell removed, showing the wiregauze chamber andits connections. Fig. 2 is a view of the chamber and supplementarycollar, and non-conducting collar removed. Fig. 3 is a verticaltransverse section of the gauze chamber and collar and non-conductin gcollar. Fig. 4 is a plan view of the non-conducting collar.

A is the wiregauze chamber, which is attached to a supplementary collar,B, which screws into the stationary collar (3, and has a female screw onthe opposite side for the reception of the non-conducting burner-collarD, which also has a screw for the reception of the burner. This collaris made of vulcanized rubher, or other suitable material, and hasperforations through the top, as shown by Fig. 4, which allows thesurplus gas to escape, and admits air to enter the chamber formed by thecombined collars, which increases the brilliancy of the flame, andprevents the blurring and smoking of the chimney. The supplementarygauzechamber collar 13 is not to be removed,except for the purpose ofcleaning 3 and for preventing it from unscrewing, when the burner isremoved for filling the lamp, a stop-spring, a, is attached to thestationary collar 0. E is the burner, which is constructed in theordinary manner, and has a wire-gauze attached over the mouth of thegas-tube, which gives additional security by preventing the possibilityof the flame entering the chamber in the neck of the burner. The partsof my invention are so constructed that they may be readily attached tothe ordinary lamp, and the chamber formed by the combined collarsobviates the liability'of the fluid to leak out from the top of the lampwhen agitated.

I do not claim, broadly, the gauze safety attachment, as I am aware thatsimilar devices have been used before; but there are some advantagesgained by my construction and combination of parts over any other ofwhich I have knowledge. For instance, it has been found objectionable toattach gauze to the collar of the lamp on account of the difiiculty incleaning the lamp, and it is not desirable that it (the gauze) shouldbeattached directly to the wick-socket, for two reasons: first, a personcannot get at the bottom of the wick-tube, nor at the lower end of thewick; and, secondly, when the gauze is so attached to the wicksocket, itconducts too much heat to the oil, both of which defects are overcome bymy construction, particularly when I make collar D of a non-conductingmaterial. It will also be observed that when the non-conducting collar Dis employed it is necessary to use the supplemental washer B, as thegauze, being of metal, cannot be properly secured to the rubber-of whichcollar D is made.

I claim as my invention 1. The herein-described safety attachment forlamps, consisting of collar 0, the metal collar B,-the gauze A, attachedto the collar 13, and the non-conducting collarD, substantially as setforth.

2. In a lamp, the combination of the collar 0, the supplemental collarB, and the frictionst p a, substantially as set forth.

STEPHEN S. NEWTON.
